ELI5, how does 2^0 power equal 1?

Question

I’m doing my GED and passed that math part but this never came up. I saw it on a meme and am lost.
Help!!??

Answer 1

Power of 0 of any number being equal to 1 is just a CONVENTION, to make math consistent.

That’s all it is to be for ELI5. Higher knowledge of limits, calculus is required for deeper understanding.

PS: Except 0^(0), that is undetermined.
